Abstract:
Objective: To investigate the value of MRI in diagnosis and differential diagnosis of benign and malignant non-mass enhancement (NME) breast lesions. Methods: MRI data of 96 patients with breast NME lesions were retrospectively analyzed. MRI features, including distribution pattern, internal enhancement characteristics, signal intensity of T2WI with fat suppression and types of time-intensity curve (TIC) were compared between benign and malignant NME lesions. And Logistic analysis was used to obtain the risk factors for malignant lesions. Results: There were 28 benign lesions and 68 malignant NME breast lesions. Statistically significant difference was found in the internal homogenous enhancement between benign and malignant lesions (P=0.026). As for the signal intensity of T2WI with fat suppression, there were significant differences in hyper and iso-signal intensity between benign and malignant lesions (P=0.025, 0.045). As for the TIC types, the differences of type and type III were statistically significant between benign and malignant lesions (P=0.013, 0.001). The risk factors of malignant lesions included iso-signal intensity of T2WI with fat suppression and type III TIC, with the odds ratio (OR) of 5.228 and 10.841, respectively. Conclusion: MRI has high diagnostic accuracy for breast cancer appeared as NME.
